This invention relates toautomatic lubrication lsystem 2 leads to various points of the chassis systems for auto vehicles'and'particularly .to syswhich are to be lubricated, such as, for instance, tems of that type in which lubricant is periodthe bearing surfaces at the ends 3, 4, 5 ofithe ically supplied simultaneously to a plurality of 'vehicle springs.

It is apparent from an inspection of Figure 2 that with the brush 13 and arm 23 in the positions shown, a circuit will be completed through themotor, operating the latter and causing the pump to bev actuated. Meanwhile the brush 14 is in open circuit position, and there is also a gap between thepoles 18 and 19 of the safety switch.

The intermediate gear l0 is provided with a pin 24, engageable with arms which extend at right Vangles to each other radially of the axis of the switch arm 23, and movable therewith. When an arm 25 is struck by the pin 24, referring now to Fig. 3 the switch arm 23 snaps over to close the gap between the poles 18 and 19. Both circuits are now open and the motor ceases to operate. The circuits remain open until the chassis travels the next hundred miles when the adjacent contact 12 comesinto engagement with the brush 14, .closingthe' circuit through the brush 14, poles 18` and 19, motor and battery,
